IB in Keens 4 and 5
Yup, my brother James, while fooling around with TED and the keens today, found that, in certain locations keen is able to rocket up on his bullet in keens 4 and 5!

"Research" is still in it's early stages :D , but one example is:
Enter Border Village in keen 4, and go to the area with the multiple one-ups under the houses. Hump onto the platform and ride it down till if flys off the screen. Don't jump, just aim up and shoot! cool, eh?

Makes sense, since they do use the same engine.

Re: IB in Keens 4 and 5
This leads me to the conclusion: the IB trick works whenever the platform that Keen is riding on is deleted (either by disappearing, for bullets in K6, or in this case by going off the edge of the level).
If the attributes for bullets in K4 and K5 were changed so that you could ride on them, then IB would be possible anytime in them also.

Forge315: The only place in Keen 4 that I'm currently aware of is the falling platform under 7 lifewater flasks in the first level.

Andrew (adurdin): so you're saying that in keen 6, Keen's bullets have attributes in common with platforms? What do you suppose makes keen "fall" off his bullet in keen 6 if another gun nearby fires?

Re: possible but where
The sprites are kept in a linked list in memory. When a sprite is destroyed (e.g. bullet hits a wall and disappears), then the item in the list it was using is removed. However, if Keen was standing on the bullet, there is still a "platform" pointer to the item that the bullet had occupied (even though it no longer exists). If a gun fires nearby, or Keen fires his gun, the newly created bullet sprite takes the first available spot in the list, which was where Keen's first bullet had been. Since the "platform" pointer is still pointing to this item, as soon as the new sprite moves, it tries to take Keen with it; but because he is no longer close enough to the sprite (when the gun fires nearby), he falls off it.

Make sense?

How come Keen 6 treats bullets as a platform?

Re: possible but where
I haven't quite tracked that down fully yet, but I expect there's an attribute that marks it as a platform (erroneously, of course, but helpfully).

Not that I like cheats, but you can fly without the bullet trick in 4/5:
Press A+2+ENTER and you can enter the same cheatcodes as in CK6 - and they'll actually have their affect!

But in Keen 6 1.0 you don't need to press those keys! ;)
Anyway, it isn't fun to fly with the cheat, impossible bullet is more fun and very cool! :)

Yes, IB is more fun, because technically, it's not cheating :p
